Energy dissipation devices are utilized in buildings to improve their resilience and safety against dynamic forces such as seismic loads. Since the most commonly used passive dampers have operational limitations due to lack of control on their performance, in recent years, engineers tend to employ adaptive hybrid dampers which could be adjusted according to the seismic demands. In this research, seismic behavior of a fifteen story building equipped with 3 tuned mass dampers (TMD) is investigated and compared with the seismic response of the same building in which 3 magnetorheological dampers (MR) are paired with the TMDs to operate concurrently with them as hybrid energy dissipating system. The MR dampers are commanded by a linear quadratic regression (LQR) control method which adjust the dampers resistance force according to the seismic displacement and velocity of the structure. This building is subjected to 5 far field earthquake records and the results display that the hybrid system can perform considerably better than passive TMDs improving the seismic demands of the structure.
